Speedway Reader IPJ-R1000 for Gen 2 UHF RFID

5.3. Accessing Tags

After acknowledging a tag, the Speedway reader may choose to access it. Under the Tag Access menu, a pull down menu

provides four command Actions: Read, Write, BlockWrite, Lock, and Kill.

The menu item Tag Access (see Figure 5-3) adds a Mask field to the filtering operation, which allows the user to mask

individual "don't care" bits or segments of the matching pattern, where "1" identifies a bit of interest and "0" represents a

masked bit.

Tag Access differs from the Inventory Filter operations in several respects. First, rather than simply continuously

inventorying a population of tags, Tag Access allows the user to automatically Halt the inventory process upon finding a tag of

interest (e.g., a tag that meets the Halt Filter criteria). At this point, the tag can be automatically read, written, locked, or

killed, according to the action selected in the Action pull-down menu. Furthermore, the action is applied only to the selected

MemBank, and within it, the desired memory rows (00−07), the rows being made up of 16-bit words. If Action calls for a

write, the specific bit pattern to be written must be entered (in hex format) in the corresponding field(s) below the selected row

number(s). Note that multiple selected rows must be contiguous.

The Tag Access view is consistent with the Operation view (described in section 5.1) in that settings applied to one are valid

for the other.
